22 Claims. (Cl. 189-75) The present invention relates to a metal window casing structure used in association with a casement type window and particularly adapted for installation in the window openings of prefabricated building structures.

It is an object of the present invention to provide a casing construction to be used in association with a casement type window that can be readily installed into the window opening of a prefabricated building structure by a clamping action against the building structure.

It is another object of the present invention to provide a casing construction comprising a room side member and a weather side member with a resilient insulating strip separating .the two members.

It is .a further object of the present invention .to provide a casing construction that can be used in association with steel casement type windows having frame bars of several dilferent size thicknesses.

It is still a further object of the present invention to provide a casing construction comprised of parts that can be shipped knocked down and be readily assembled in the field.

. 'Figure8 is a perspective view partly broken away of a corner of the room side member of the casing partially assembled.

Figure 9 is another modified form of the invention of a section'similar to that shown in Figure 2.

Referring now .to the drawings, 10 shows a wall portion of a prefabricated building structure with the casing The 2,773,571 Patented Dec. 11, 1956 be any of the conventional types of solid section steel bars used in steel windows. The wall 10 of the building structure can be fabricated from metal, plywood or any type of construction used in prefabricated wall panels or structures and has an opening 20 of a predetermined shape and size to suit the casing assembly.

The weather side assembly 22 of the casing 12 comprises a head member 24-, sill member 26, and two jamb members 28. The head, sill and jamb members are identical in cross-section and each comprises a channel shaped molding 30 having an outer leg 32, an inner leg 34, and an intermediate connecting wall 36. The outer leg has a return bent portion 38 terminating in a wall 40 bent toward the building structure to form a groove 42 for receiving a resilient strip 44. The strip 44 can be rubber, plastic, felt or any material that has resilient and insulating qualities. The wall 34 turns slightly downwardly toward the building structure and thence inwardly where it is shaped to form the walls 46 and 48 providing a corner for locating the member against the corner of the window opening 20. The head member continues inwardly of the opening to provide a wall 50 forming an abutment against which the window frame bar 16 abuts and wall 52 forming a seat for .the window frame bar. The wall 52 inclines outwardly as shown at 53 and then toward the room side and terminates in the edge 54 that extends in a straight line along the length of the casing. Apentures 56 provide attachment means for the frame bar to head member 24 by screws 57. Weep hole 58 provides a drain for any moisture that may collect inside "the molding 30. A drip 59 hooks over the sash fram bar at the head, as best seen in Figure 2.

The room side assembly 60 of the casing 12 also comprises a head member 62, a sill member 64, and two jamb members 66. The head, sill and jamb members are identical in cross-section and each comprises a channel shaped molding 70 having an outer leg 72 and an inner leg 74 connected by an intermediate wall 75. The outer leg is bent at right angles to form the terminal portion .76 that extends along the length of the casing at substantially parallelism to the building structure. The leg 74 is reversely bent at 78 and then shaped to form the grooved channel 80. A resilient and insulating strip 82 is received in the groove. Countersunk apertures are provided for attachment.

It will be noted that edge portion 54 overlies both strip 82 and groove 80, and serves to center the room side assembly including the resilient strip 82.

Clips are used to assemble the room side and weather side portions of the casing to each other and to the building structure at the window opening by means of screws 92. The clip is attached to the weather side casing by means of the screws 57 which also serve to hold the window frame bar to the casing. A washer 96 is positioned between the clip and easing portion 52. The clip 90 is formed generally U-shaped with legs 98 and 100 connected by the portion 102. The portion 104 extends at substantially 45 degrees to the leg 98 to engage the inclined surface 53. Holes 106 and 108 are tapped with threads to receive screws 57 and 92 respectively.

' Before insertion into the window opening of the building structure the head member 24, sill member 26, and two jamb members 28 are all assembled together into one unit. An interfitting construction is provided at each corner. Referring to Figure 7, the outer leg 32 of the weather side jamb member is cut off at 122 substantially at right angles to the length of the casing and thence cut inwardly as seen at 124, at an angle of 45 degrees to the leg 34 which is cut at right angles to the length of the casing, as seen at 128. Wall 46 is cut away at 132 and walls 48, 50, 52, 53 and 54 are cut away leaving edges 136, 138 and 140.

The head member 24 has legs 32 and 34 and wall 36 cut to match the corresponding'legs and wall of the jamb member to allow them to abut each other when assembled to form the mitre joint 144, as best seen in Figure 3. The member is further out back at 146 and 148 to provide surfaces 150 and 152 which abut 132 and 136 respectively of the jamb member and to provide end surface 151. As best seen in Figure 3, an open space 154 is left at the corner which is covered by the Window frame bars. Thi space provides clearance for pivoted ends, welds or other protuberances at the corner construction of the window frame.

A channel shaped connecting member 160 is attached to the inner surfaces of the channel portion of the head member as by welding with two legs 162 and 164 of the member 160 being bent at right angles so as to register with the inner surfaces of the legs 32 and 34 of the jamb member to retain the head and jamb members in interfitting relation. The corner at the sill is identical to the corner just described with the connecting member 160 being attached to the sill member and having legs corresponding to legs 162 and 164 engaging the inner surfaces of legs 32 and 34 of jamb members 28.

The room side jamb member 66, as best seen in Figure 8, has a straight edge portion 170 with the two walls '76 and 75 cut back at substantially 45 degrees, as seen at 173 and 175 respectively. The wall 74 is cut off at 90 degrees to the length of the casing at 178 and 180 to leave the tongue 182. The channel 80 is also cut off in line with the edge 180.

The room side sill member 64 which is identical in cross-section to the jamb member is cut off at 186, 188, and 190 to abut the corresponding edges on the jamb member to form a mitre at the room side similar to the mitre joint 144. The slot 194 is provided for the reception of the tongue 182. The grooved channel 80 of the sill is cut off at 198 to abut the inner side of channel 80 when the corner is assembled.

The assembling member 200 is attached to the sill member 64 by welding as seen at 201, or any suitable means. Portion 202 of the assembling member engages the wall 74 of the jamb member and portion 204 slides inside the groove formed by walls 75, 72, and 76. The corner at the jamb and head is identical with the corner above described with a member 200 being attached to the head.

The weatherside head, sill and jamb members are assembled together by the interfitting means provided. The window is installed on the weather side casing assembly with the drip S9 in place by means of clips 90 and screws 92. There are sufficient clips and screws provided to securely hold the window in place, preferably two of each to a side. The screws and clips in association with the window frames also hold the weather side casing members together so that no interlocking means are necessary at the corners. The insulating strips 44 are inserted in the grooves of each member and held in place preferably with an adhesive.

Before placing the assembly into the window opening, caulking material 206 is placed along the corner formed by walls 46 and 48 and with the weather side of thecasing in place the caulking serves to hold the casing away from the building structure and retain any moisture that may find its way inside the casing. The leg 100 of the clip 90 is bent slightly outward with its terminal edge contacting the building structure and centers the assembly in the opening. The leg 100 has enough resiliency to take up any dimension variations in the window openings of the structures. The inclined portions 104 of the clips contact inclined wall portion 53 and holds the clip from rotating when the screw 94 is being tightened.

The room side head, sill and jamb members are assem bled together in the manner provided with the tongue 182 being bent over when inserted through the slot 194. The insulating strips 82 are inserted in the grooves provided and held secure by an adhesive. The room side assembly is held in place in the window opening by screws 92, there being a screw for each clip used. The screws 92 around the periphery of the casing are tightened an amount sufiicient to draw up the resilient insulating strips against adjacent members they abut to provide a seal. The excess caulking material is squeezed out from along the corner. The terminal portions 76 bear against the room side wall of the building structure to secure the casing and window assembly in place by a clamping action. it will noted that no screws or other fastening devices perforate the building structure. The insulating features of the casing do not allow any substantial heat conducting path between the interior and exterior of the building structure. the only path being provided by clips and screws 92, which conduct a negligible amount of heat.

in Figures 5 and 5A a modified form of the invention is shown. The building structure 10 is the same as previously described. Weather side frame members 211 have resilient insulating strips 212 of a bulbous form with a slot 213 along one side fitting over the bent-over terminal edge 214 of the casing, as best seen in Figure 5A. The room side frame members have insulating strips 216 which are the same as strips 212 and fit over the terminal edges 213. The opposite terminal edge portions 200 of the room side frame members are bent toward the weather side of the opening and act to locate the casing member along the corner of the building structure. The casement window structure shown is composed of bars 219 of larger section than those shown in Figure 2. When the larger bars 21.9 are used, wall 222 corresponding to wall 46 of Figure 2, provides an abutment against which the edge of bar 219 bears.

Figures 6 and 6A show another modified form of the invention. In this case, the resilient insulating strips 230 and 231 are of identical bulbous construction with a slot along one side. The terminal edge portions 232 of the frame members are return bent at a slight angle to the wall 234 to provide an edge to retain the strip in place. Wall portion 240 of the weather side head member is return bent at a 45-degree angle to form the wall 242 providing a drip for the head member of the casing.

Figure 9 shows the casing adapted for use with wood stud framing type of building construction having sheathing 250, studs 252, and either dry wall or plaster 254 on the interior finish. The weather side head member 260 has a nailing flange 262 provided with apertures located at spaced intervals along the length of the flange through which nails 266 are driven. The building paper 268 laps over the nailing fin for weatherproof construction. The clip 280 corresponds to clip 90 previously described and has a portion 282 extending toward the room side of the casing and a right angle bent portion 284. Tapped holes therein receive the screws 290 and 292. The clip is of the same width as clip 90 and also serves to center the room side member in the opening 294. The room side member 300 has a terminal edge portion 302bent over at right angle from the portion 304 and fits into a groove of the resilient insulating strip 306 that runs along the length of the casing. Details of the insulating strip may be as seen in Figures 2, 5A or 6A. The head, jamb, and sill members are preferably the same in cross-section for both room side and weather side members and are joined at their ends to each other with a corner construction similar to that shown in: Figures 7 and 9.

After the weather side members are joined together by their interfitting construction at the corners, the window frame bars 310 are placed in the assembly and secured in place by screws 290 and clips 280 with the drip 312 in place on the head member. The assembly is then placed in the opening 314 of the building structure. After the assembly is squared and centered it is secured in place by the nails.

Theroom side members are then joined together by the interlocking and interfitting corner construction with the plied and then the room side assembly may be secured. 1

With dry wall plaster construction it is especially desirable to assemble the room side member after applying the dry wall so that the member can be drawn up tightly against the wall leaving no cracks. Also, with plaster construction the problem of keying the plaster to the casing is eliminated when the casing is applied after the wall has been completed. The resiliency of the insulating strips allows them to be drawn against the window frame and against the terminal edges 320 of the weather side members to provide a seal to keep dirt and moisture from 4 inside the casing. The insulating strip does not allow any heat conducting path between the interior and exterior of the building with the exception of the clips and screws 292. These are used preferably two to each side of the casing except in large installations where more may be desirable, and in any case conduct a negligible amount of heat between the weather, and room side assemblies.

In the foregoing constructions it will be observed that the corners of the room side frame are interlocked by tongues 182 and slots 194. The corners of the weather side frame however, merely frictionally interfit upon assembly, but are rendered rigid by insertion of an interlocked rigid rectangular window frame composed of frame bars 16.

The drawings and the foregoing specification constitute a description of the improved window casing construction in such full, clear, concise and exact terms as to enable any person skilled in the art to practice the invention, the scope of which is indicated by the appended claims. a
